Engineering 4 Kids - Spy with a Periscope

Peek around corners without being seen. A periscope allows you to look almost anywhere while hiding behind walls, furniture, doors - wherever.

To make a periscope you need:

a one liter milk carton
scissors
two small rectangular purse-sized mirrors
masking tape

Directions:

Cut the pointed end off the carton.
Cut a 7 cm square from one side at the open end of the carton, near the top.
Tape your cut out square to where the spout was to make a flat top.
Tape a mirror inside the hole at a 45 degree angle, the reflective side facing the bottom of the carton.
Cut a 7 cm square from the opposite side of the carton at the bottom
Tape the other mirror, reflective side facing the first mirror, inside this hole at a 45 degree angle.

Look through the bottom hole and start spying!
